Afghan-US relations under strain

Thousands of Afghans have taken to the streets of Kabul for a second day, outraged after learning that copies of the Koran were burnt at a US airbase. Bagram detention centre is at the heart of the controversy, long despised by many Afghans and even described as Afghanistan's own Guantanamo. President Karzai has renewed calls for it to be placed under Afghan control. Following on from another recent incident with US troops, diplomatic relations are under increasing strain.
